the primary throwing device comprises a throwing knife roller, a throwing shell and a driving belt pulley, the driving belt pulley drives the throwing knife roller to rotate, the throwing knife roller is positioned in the throwing shell, and the throwing knife roller throws out the green stored crushed aggregates entering the throwing shell through rotation; two circles of throwing blades are obliquely and alternately arranged on the throwing knife roller, each circle of throwing blades consists of a plurality of independently arranged throwing blades, the top of each throwing blade is an arc-shaped blade end face, and each point on the arc-shaped blade end face is equal to the gap between the inner walls of the throwing shell;

the grain crusher comprises a crusher side plate, a fixing plate, a front side plate, a movable crushing roller, a fan, a connecting barrel, a transmission arm and a transmission shaft, the grain crusher is fixed on the rack through the fixing plate, the transmission arm drives the movable crushing roller to rotate through the transmission shaft, the movable crushing roller drives the crushing roller to rotate, the fan is positioned above the crushing roller, a square inlet at the bottom of the connecting barrel is connected with the crusher side plate and the front side plate, and a round inlet at the top of the connecting barrel is connected with the throwing pipe; the movable crushing roller and the crushing roller are enlarged crushing rollers;

the secondary throwing device is arranged in front of a throwing port of the primary throwing device, and the distance between the secondary throwing device and the primary throwing device enables the secondary throwing device to provide throwing power for the object thrown by the primary throwing device again, wherein the angle between the throwing direction of the secondary throwing device and the throwing direction of the primary throwing device is 0-90 degrees; the secondary is thrown and is sent the device and include: the device comprises a rotating shaft and a roller mechanism arranged on the rotating shaft, wherein two circles of throwing blades which extend inwards by taking two end parts of the roller as initial positions are arranged on the outer side of the roller mechanism, any one of the two circles of throwing blades and the adjacent throwing blade on the other circle of throwing blade are distributed in a staggered mode and are in a V shape, and the inner end parts of the throwing blades extend out to increase the overall length of the throwing blades and improve the contact area between the throwing blades and a material to be thrown; a rib plate is arranged between the roller and each throwing blade, so that the connection stability of the throwing blades and the roller is enhanced, and the service life of the throwing blades is prolonged; the length of each throwing blade is greater than half of the length of the roller and less than the length of the roller, the total length of the throwing blades is increased, the characteristics of each throwing blade are consistent, the processing and mounting precision is improved, and the rotating stability of the secondary throwing device is enhanced; each circle of throwing blades comprises 4-6 throwing blades, and the included angle between each throwing blade and the axis of the roller on the roller is 5-15 degrees, so that the throwing speed is improved; the outer edge of each throwing blade along the length direction is in a sawtooth shape, and when the throwing device is applied to a green fodder harvester, the sawtooth-shaped design has a material scraping effect, can clean the adhered green fodder on the throwing cylinder and is beneficial to driving the chopped green fodder; the pressure roller is arranged in the area above the delivery roller and transports the material to the upper part of the conveying groove of the conveying mechanism;

the conveying trough is used for conveying materials, and the disc cutter chopper and the seed crusher are arranged on the rear side of a front axle of the whole vehicle, so that the balance weight of the whole vehicle is facilitated;

the material is thrown and sent to the seed grain breaker on upper portion, through the broken crushing roller that rolls of seed grain that has the velocity difference, after throwing the forced draught blower to accelerate the material through the secondary, throw and send the material to the car that connects the grass and transport and store through throwing.

2. The working method of the self-propelled green fodder harvester provided with the disc cutter type chopper as claimed in claim 1 comprises:

the material is pre-pressed and kneaded by utilizing the rotation motion of the pressure roller, and is conveyed to the disc type shredder through the conveying mechanism to be shredded and then recovered.
